If\naie2_populate_range() runs concurrently, it may obtain a reference to an\namdxdna_umap that is being released, leading to a potential use-after-free.\n\nUse kref_get_unless_zero() in aie2_populate_range() when acquiring a\nreference. If the reference count has already dropped to zero, release\nis in progress and the entry is skipped.","published":"2026-08-15T06:22:05.873","modified":"2026-08-17T06:18:36.353","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/14f172eff9c19f8043a9858845f33cd034f3a41e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/267809e2c56fbea486f7250c8a4acddcc3c54dc5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91e8109ecffb925b6202d2737384df285b195bfb"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T06:18:36.353"}}
